localrepo: store path and vfs location of cached properties

This information is used to make transaction handle these files
specially, in order to avoid file stat ambiguity of them.

Gathering information about cached files via annotation classes can
avoid overlooking properties newly introduced in the future.

test --time

  $ hg --time help -q help 2>&1 | grep time > /dev/null
  $ hg init a
  $ cd a


test --profile

  $ hg st --profile 2>&1 | grep Sample
  Sample count: \d+ (re)

Abreviated version

  $ hg st --prof 2>&1 | grep Sample
  Sample count: \d+ (re)

In alias

  $ hg --config "alias.profst=status --profile" profst 2>&1 | grep Sample
  Sample count: \d+ (re)

#if lsprof

  $ prof='hg --config profiling.type=ls --profile'

  $ $prof st 2>../out
  $ grep CallCount ../out > /dev/null || cat ../out

  $ $prof --config profiling.output=../out st
  $ grep CallCount ../out > /dev/null || cat ../out

  $ $prof --config profiling.output=blackbox --config extensions.blackbox= st
  $ grep CallCount .hg/blackbox.log > /dev/null || cat .hg/blackbox.log

  $ $prof --config profiling.format=text st 2>../out
  $ grep CallCount ../out > /dev/null || cat ../out

  $ echo "[profiling]" >> $HGRCPATH
  $ echo "format=kcachegrind" >> $HGRCPATH

  $ $prof st 2>../out

  $ $prof --config profiling.output=../out st

#endif

#if lsprof serve

Profiling of HTTP requests works

  $ $prof --config profiling.format=text --config profiling.output=../profile.log serve -d -p $HGPORT --pid-file ../hg.pid -A ../access.log
  $ cat ../hg.pid >> $DAEMON_PIDS
  $ hg -q clone -U http://localhost:$HGPORT ../clone

A single profile is logged because file logging doesn't append
  $ grep CallCount ../profile.log | wc -l
  \s*1 (re)

#endif

Install an extension that can sleep and guarantee a profiler has time to run

  $ cat >> sleepext.py << EOF
  > import time
  > from mercurial import registrar, commands
  > cmdtable = {}
  > command = registrar.command(cmdtable)
  > @command(b'sleep', [], 'hg sleep')
  > def sleep(ui, *args, **kwargs):
  >     time.sleep(0.1)
  > EOF

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > sleep = `pwd`/sleepext.py
  > EOF

statistical profiler works

  $ hg --profile sleep 2>../out
  $ grep Sample ../out
  Sample count: \d+ (re)

Various statprof formatters work

  $ hg --profile --config profiling.statformat=byline sleep 2>../out
  $ head -n 1 ../out
    %   cumulative      self          
  $ grep Sample ../out
  Sample count: \d+ (re)

  $ hg --profile --config profiling.statformat=bymethod sleep 2>../out
  $ head -n 1 ../out
    %   cumulative      self          
  $ grep Sample ../out
  Sample count: \d+ (re)

  $ hg --profile --config profiling.statformat=hotpath sleep 2>../out
  $ grep Sample ../out
  Sample count: \d+ (re)

  $ hg --profile --config profiling.statformat=json sleep 2>../out
  $ cat ../out
  \[\[-?\d+.* (re)

statprof can be used as a standalone module

  $ $PYTHON -m mercurial.statprof hotpath
  must specify --file to load
  [1]

  $ cd ..

profiler extension could be loaded before other extensions

  $ cat > fooprof.py <<EOF
  > from __future__ import absolute_import
  > import contextlib
  > @contextlib.contextmanager
  > def profile(ui, fp):
  >     print('fooprof: start profile')
  >     yield
  >     print('fooprof: end profile')
  > def extsetup(ui):
  >     ui.write('fooprof: loaded\n')
  > EOF

  $ cat > otherextension.py <<EOF
  > from __future__ import absolute_import
  > def extsetup(ui):
  >     ui.write('otherextension: loaded\n')

  $ hg init b
  $ cd b
  $ cat >> .hg/hgrc <<EOF
